| 英文摘要 | The current situation of geochemical studies on coalbed gas is reviewed in this paper. Generally, coalbed gas is compositionally dominated by methane with delta C-13(1) values ranging approximately from -80 parts per thousand to -10 parts per thousand. However, few isotopic studies have been carried out on other components of coalbed gas except for hydrogen and carbon dioxide, whose delta D-CH4 values available for utilization vary from -333 parts per thousand to -117 parts per thousand, and delta C-13(CO2) values from -29.4 parts per thousand to + 18.6 parts per thousand. Two major types of coalbed gas, thermogenic gas and secondary biogenic gas, have been identified, and there are also some other classification criteria. Compared with conventional natural gases, coalbed gas has a wide distribution range of delta C-13(1) and delta C-13(CO2) values, especially possessing some extremely heavy values. Current problems that remain unsolved in the coalbed gas geochemistry include the variation mechanism, controlling factors and application of carbon and hydrogen isotopes of methane, the relation between the values of delta C-13(1) and Ro, the systematic classification scheme and criterion of genetic types, and the application of the coalbed gas geochemistry in evaluating target districts of the coalbed gas exploration. |
